    containers: modify bindmount option · bb515496
    Guillaume Abrioux authored
    This commit changes the bind mount option for the mount point
    `/var/lib/ceph` in the systemd template for mon and mgr containers. This
    is needed in case of collocating mon/mgr with osds using dmcrypt
    scenario.
    Once mon/mgr got converted to containers, the dmcrypt layer sub mount is
    still seen in `/var/lib/ceph`. For some reason it makes the
    corresponding devices busy so any other container can't open/close it.
    As a result, it prevents osds from starting properly.
    
    Since it only happens on the nodes converted before the OSD play, the idea is
    to bind mount `/var/lib/ceph` on mon and mgr with the `rshared` option
    so once the sub mount is unmounted, it is propagated inside the
    container so it doesn't see that mount point.
